1. Product Instruction
MK05 series is a powerful, highly flexible, ultra low power Bluetooth® 5 module based on Nordic®
Semiconductor nRF52810 SoC solution, which has a 32bit Arm® Cortex™-M4 CPU with floating point
unit running at 64MHz.
MK05 module is multiprotocol capable with full protocol concurrency. It supports BLE® (Bluetooth
Low Energy) and 2 Mbps of Bluetooth 5 giving increased application throughput and up to 50 %
savings in energy usage. It supports channel selection algorithm #2 (CSA#2), improving the ability
to coexist with other Bluetooth LE devices. 2.4 GHz proprietary protocols are also supported.
1.1 Model Classification
There are two models of MK05 series Bluetooth module — MK05A and MK05B. The two models
both have a small size of 21 x 13.8 x 2.3mm with all 30 GPIOs of nRF52810QFAA (QFN48 package).
The difference between MK05A and MK05B is the antenna design.
MK05A integrates a high-performance PCB antenna.
MK05B uses a u.FL connector and requires an external 2.4Ghz FPC antenna.
